Agricultural feed bagging machine

ABSTRACT

An improved agricultural feed bagging machine for bagging feed materials in a bag including a rearwardly extending tunnel having elongated and arcuate spaced-apart ridges provided on the inside surfaces of the side walls of the tunnel to create turbulence in the flow of feed, thereby resulting in a greater compaction of the feedstuffs in the bag.

CROSS-REFERENCE TO RELATED APPLICATIONS

This is a continuation-in-part application of Ser. No. 08/003,540 filedJan. 13, 1993, U.S. Pat. No. 5,297,377 which is a continuation-in-partapplication of application Ser. No. 07/912,873 filed Jul. 13, 1992.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an agricultural feed bagging machine and moreparticularly to an agricultural feed bagging machine having means on theinside surfaces of the tunnel to create turbulence in the flow ofmaterial passing thereby to increase the compaction of the feedstuffs inthe agricultural bag.

2. Background Information

Agricultural feed bagging machines have been employed for several yearsto pack or bag silage or the like into elongated plastic bags. Two ofthe earliest bagging machines are disclosed in U.S. Pat. Nos. 3,687,061and 4,046,068. In the prior art bagging machines, silage or the like issupplied to the forward or intake end of the bagging machine and is fedto a rotor which conveys the silage into a tunnel on which the bag ispositioned so that the bag is filled. As silage is loaded into the bag,the bagging machine moves away from the filled end of the bag in acontrolled fashion so as to achieve uniform compaction of the silagematerial within the bag. In U.S. Pat. No. 4,337,805, silage is forced bymeans of a rotor from the intake chamber of the machine through theoutput chamber of the machine and into the agricultural bag with abackstop structure yieldably engaging the closed end of the agriculturalbag to resist the movement of the bagging machine away from the filledend of the agricultural bag as silage is forced into the bag. Thestructure of the '805 patent includes a pair of drums rotatably mountedon the bagging machine with a brake associated therewith for braking orresisting the rotation of the drum with a selected brake force. A cableis wrapped around the drum and is connected to the backstop.

Although the cable drum and backstop structure of the '805 patent andother similar machines do function generally satisfactorily, the cables,which are positioned on opposite sides of the bag, can create openingsor holes in the bag which will adversely affect the fermentation processwithin the bag. A further disadvantage of the cable drum and backstopstructure of the devices such as shown in the '805 patent is that thecables must be rewound after the filing of an individual bag. A furtherdisadvantage of the cable drum and backstop structure of the machinesuch as disposed in the '805 patent is that a dangerous condition existsshould one of the cables break.

In an effort to overcome some of the disadvantages of machines such asdisclosed in the '805 patent, an attempt was made in U.S. Pat. No.4,621,666 to achieve the desired bagging operation while eliminating theneed for the cable drum and backstop structure. In the '666 patent, thewheels on the bagging machine were braked to provide the desiredresistance to the filling of the bag. Although the brake system of the'666 patent apparently met with some success, it is believed thatmachines such as disclosed in the '666 patent experience slippagedifficulties in wet field conditions which adversely affect the baggingoperation. It is also believed that the brake means alone on the baggingmachine such as those disclosed in the '666 patent do not achieve thedesired compaction of the silage material within the bag.

In applicant's co-pending application, Ser. No. 07/912,873, a baggingmachine is described which has the capability of enabling the density ofthe silage material to be selectively controlled without the need of anelaborate braking system. Although the bagging machine of Ser. No.07/912,873 does satisfactorily achieve all of its objectives, a moresimple way of controlling the density of the bagged material wasdiscovered and was the subject of the patent application, Ser. No.08/003,540. Although the density control means described in Ser. No.08/003,540 did represent a significant advance in the art, it isbelieved that the instant invention likewise represents a significantadvance over the prior art.

In the co-pending application, Ser. No. 08/003,540, a density controlmeans was described which included a plurality of cables which werepositioned in the flow of the silage material being bagged. In order tovary the density of the material in Ser. No. 08/003,540, more or lesscables would be employed based on the material being packed. Forexample, corn silage flows easy and would require more cables whilealfalfa packs hard and would use less cables. The need to have anon-the-spot variable cable density has existed and the instant inventionprovides such a feature.

Although the density control means of the co-pending applications doperform extremely satisfactorily, it has been found that the compactionof the feedstuffs within the agricultural bag can be enhanced throughthe utilization of a plurality of spaced-apart ridges located on theinside surfaces of the side walls of the tunnel.

SUMMARY OF THE INVENTION

An agricultural feed bagging machine is disclosed which comprises awheeled frame having rearward and forward ends. A tunnel is provided onthe wheeled frame and has an intake end for receiving silage materialand an output end adapted to receive the mouth of an agricultural bag. Ahopper is provided on the wheeled frame for receiving the silagematerial and is adapted to supply the same to a rotatable rotor whichforces the silage into the tunnel and into the bag. At least oneU-shaped cable is positioned in the tunnel for controlling the densityof the material being compacted within the bag.

In the instant application, a plurality of spaced-apart ridges areprovided on the inside surfaces of the side walls of the tunnel. Thefeed is forced outwardly towards the side walls of the tunnel by thedensity control cable or cables with the tunnel ridges creating aturbulence in the flow of feed thereby resulting in a tighter compactionof feedstuffs within the bag.

It is therefore a principal object of the invention to provide animproved agricultural bagging machine.

A further object of the invention is to provide an agricultural baggingmachine including means for increasing the compaction of feedstuffswithin the agricultural bag.

Yet another object of the invention is to provide an agriculturalbagging machine having a plurality of spaced-apart tunnel ridges securedto the inside surfaces of the side walls of the tunnel.

These and other objects of the invention will be apparent to thoseskilled in the art.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The numeral 10 refers to an agricultural bagging machine which issubstantially conventional in design except for the density controlmeans positioned within the tunnel as will be described hereinafter.

Machine 10 includes a wheeled frame means 12 having a tunnel 14 mountedthereon upon which is normally positioned the open mouth of aconventional agricultural bag. Although the preferred embodimentincludes a wheeled frame means, a non-wheeled frame means could beemployed. For purposes of conciseness, the power means for driving thevarious components of the machine have not been disclosed since the samedoes not form a part of the invention. The power means could be anengine mounted on the machine or a PTO shaft connected to a tractor PTO.

For purposes of description, the bagging machine 10 will be described asincluding a forward end 16 and a rearward end 18. Bagging machine 10includes a hopper means 20 at the forward end thereof which is adaptedto receive the material to be bagged from a truck, wagon, etc. Arotatable rotor 22 of conventional design is located at the lower end ofthe hopper means 20 for forcing the materials to be bagged into thetunnel 14 and into the bag B in conventional fashion.

A density control means 34 may also be provided in the tunnel 14 is sodesired. Although FIG. 1 illustrates a pair of density control cablesbeing utilized, a single density control cable will normally suffice inmost situations wherein the turbulence creating ridges are utilized aswill be described hereinafter.

In FIG. 1, hydraulic cylinders 26 and 38 are operatively connected todensity control cable 34 having cable portions 54, 56 and 58. Densitycontrol cable 60 is also provided and has its ends suitably anchoredsuch as indicated at 62.

For purposes of description, tunnel 14 will be described as including atop portion 40 and opposite side walls 42 and 44. The inside surfaces ofside walls 42 and 44 are each provided with a plurality of spaced-apartridges R1, R2 and R3 which are in the shape of elongated, arcuatesemi-circular members. As seen in FIG. 1, each of the ridges R1, R2 andR3 extend upwardly and rearwardly from their lower ends towards theirupper ends. As also seen in FIG. 1, the ridges R1, R2 and R3progressively decrease in length from the forward end of the tunnel tothe rearward end of the tunnel. At least one density control cable isprovided within the tunnel 14 as previously described. One type ofdensity control cable is described in my co-pending application, Ser.No. 07/912,873, filed Jul. 13, 1992.

As the feed flows through the tunnel, the density control cable orcables force the feed outwardly towards the side walls of the tunnel andtowards the spaced-apart ridges R1, R2 and R3 located on each of theside walls of the tunnel. The ridges create a back force on the flow offeed as illustrated by the arrows in FIG. 3 to increase the compactionof the feedstuffs in the bag. As stated, the ridges increase thecompaction of the feedstuffs within the bag due to the fact that theycreate turbulence in the flow of feed thereby. Although the ridges R 1,R2 and R3, which are located on both of the inside surfaces of the sidewalls of the tunnels, do work well by themselves, it is preferred thatthe ridges be used in combination with a density control means such asdisclosed in the co-pending applications.

Thus, it can be seen that the invention accomplishes at least all of itsstated objectives.
